Nerdy by day, naughty by night! Nathan Wright has a secret life. During the day he’s a dedicated student, working hard for his maths degree. But times are tough, and in order to make ends meet by night he becomes “Einstein”, wooing punters with his online solo sex show. Still wounded by his last dysfunctional relationship, Nathan’s happy being single. But when his highest tipping client demands it, Einstein has to overcome his social awkwardness to rope in some extra help.

Party boy Rory Jones has never given his geeky neighbour a second glance, but he’s not one to turn down the offer of a free blow job, even when Nathan tells him it’s going online. Once on camera, Rory discovers his exhibitionist streak and the two of them are so hot together, the one-off becomes a regular gig. But being neighbours with benefits isn’t without its challenges. Nathan’s client keeps wanting more, and he finds himself pushed into a role he’s not prepared for. Meanwhile Rory’s growing affection leaves him worried his ultra-rational lover won’t ever be able to share his emotions. If he and Nathan can’t find something more than great sex in common, they’ll be left with the square root of absolute zero.
